Sorry Adai, I need to contradict you.
Protection Manager will not create vFiler DR configurations. In fact, if you create vfiler DR configurations in your environment, that causes problems with Protection Manager. vFiler DR creates vFiler units and volumes with identical names and in some contexts, we don't show you enough context to figure out which volume you're working with. This leads to issues where it's very easy to select the wrong volume.
Protection Manager will happily let you use different vFiler units for your primary and DR storage and gives you single-button failover. This essentially matches what vFiler DR implements but it's not using vFiler DR.
